' Specification of Application filed September To all whom it'ma'y concern:

Be it known that I, BRUCE FORD, a citizen of the United States, residing-at Philadel phia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electric Storage Batteries, of which the following is a specification.

The principal object of the present inventlon is to provide a battery cell or jar capable of being inverted without spilling its fluid contents and adapted to permit ofthe escape from its interior of. gases and vapors. 7

Another objectof the invention is to providea simple, light and comparatively iriexpensive type of storage battery especially adapted to uses in which it is subjected to rough transportation and usage. I

To these and other ends hereinafter set .l'orth the invention comprises the improvements to be presently described andfinally scope of my invention will be more fully understood trom the following description takenin 'connectionwith the accompanying drawings torming part hereof, and 1I1Wl1lClljections 8, extending upward .from the ot'-- l igure '1, isa top o'rfplan'view of a storage battery embodying features of the invention.

l lig. 2, is a sectional view taken on the line- 22 o l' Fig, 1, and Fig. 3 taken on the line 3-3 of Fig. -1. In the drawings the battery jar 1, is sub diyided into a plate'cornpartrnent 2, and an overflow eompartinentfi3, having communica is a sectional View tion with each other by way of an opening 4,

and each being closed except as wil inafterdescribed. i I v 5, and 6,ar'e tubes each communicating with the coInpart-Inent-3,--and oppositely arrangedtherein andwhere'of one 5, comr'n'uni cates-with' the CODlPtI-tllilltQ, and the other be here- 6, with the'outs'id'e of the jar.

receptacle may be appropriately made of 1 celluloid and provided with proper busl ngs as ot' soft rubber 11,.for securing'a tight oint at the lugs orterminals 9.

. 12. indicates a detachable plug arranged be reinforced as at 13, for this purpose.

13, is a soft rubber gasket arranged;be} tween the plug and the top wall of the receptacle 3. i V

The opening 4, and tube 6, are shown as arranged out of 'alinement, The plates 7, which rest upon the projections 8, are when the jar is inverted supported by the structure which constitutes the overflow compartment and-which is secured to the jar. Liquid'rnay be introduced into the plate 3, and thence pass by way of the opening 4, into the compartment 2. Vapors and'gases erse' the. tube-5, esca e into the compartment -3, and thence trave through the tube 6 and escape into the outer air. .W'lule at the'same and reach the tube 6. If the batteryjar be turned upside down or inverted, the electr'olyte Will-flow from the plate compartment 2, into the'- overflow compalrtnien'tfi, from which,' however, it may not esca e.-'beca us eits level in the compartment 3 wi notbe as high as the open end of the tube 6. Y en the jar is'again righ'ted the acid 01'- electrolyte passes through the opening 4 and eturns tothe com artment j'Z, while the tube 5'serv'es asa vent'for' permitting of the-escape, of gas; ,Vap'or'a'nd air from-the corn 'artrnent 2 4st) that the return of'theelectro y'te. is not-"1m peded or interfered-with, v Having-thus describednthenature andobjects 'of my -invention 'what' I v 'cIairnas-neiv and desire .to sec'u'refby Letters Bat t 1 invertible batt'eryf j ar sub into: lntercomrnun'icating superposed flow and platepoinpartments andp W "QPP Q Y w 'edtve municat ng' J ith the overflovv'jcom and-respectively with'the :late andwithfltliebutsidefoft e1 i an the latter'BXten'ds-into the-'ovei'fl' in the topwall of the receptacle 3, which may arising from the'compartment 2, may trav-' n ert ble-tattere-w re a. eoverf i'r'ij e -ti ation w th a .compartme'nt 2, by removing the plug.1,2','so.- that the liquid may enter the compartment,

adapted to break up the wash as the fluid g contents of the jar flow from end to end w hen the jar is inverted, substantially as de-i scribed. v
